Citing the NASA Exoplanet Archive With Digital Object Identifiers (DOI)
The archive provides Digital Object Identifiers, or DOIs, for authors to use in their published works for citation purposes. A DOI provides a persistent and standardized link to the archive data and services that enabled an author's research.
For additional information on using DOIs, consult the DOI Wikipedia page and the DOI Handbook.

| Resource Name | Description | Data Type | DOI |
|---|---|---|---|
| Planetary Systems Table | This table displays all solutions for planet and host stars, regardless of their relationship. This includes atypical systems such as free-floating planets and those with multiple stars. This table also contains Kepler, K2, and TESS candidate solutions for confirmed planet systems, a nearly complete identification of published stellar companions, and projected and true planet obliquities.
This table replaced the Confirmed Planets and Extended Planet Data tables, which was retired in April 2021. Some user interface elements in this table are different from other Exoplanet Archive interactive tables. |
Dataset | 10.26133/NEA12 |
| Planetary Systems Composite Parameters Table | Same data as the Planetary Systems table except the confirmed planet data includes parameters or calculations that are combined from different references into one parameter set, or row. References are given for each value. Use this table when you need a more "filled-in" table to enable a statistical view of the known exoplanet population and their host environments. This table replaced the Composite Planet Data Table, which was retired in April 2021. Some user interface elements in this table are different from other Exoplanet Archive interactive tables. |
Dataset | 10.26133/NEA13 |
| HWO ExEP Precursor Science Stars (Also known as Habitable Worlds Observatory Preliminary Input Catalog, or HPIC) |
This is a list of ~13,000 bright, nearby objects from TESS and Gaia DR3 that are potential targets for space-based direct imaging with the Habitable Worlds Observatory. | Dataset | 10.26133/NEA39 |
| Stellar Hosts Table | This table lists all of the stellar parameters for a planetary system currently in the Exoplanet Archive. These data are a superset of what is available in the Planetary Systems and Planetary Systems Composite Data tables. In addition to listing stellar solutions associated with a given planetary solution (as is the case for the Planetary Systems table), the stellar parameters table also includes stellar parameters that are in the Exoplanet Archive for a planet hosting star but the parameters are not associated with a specific planetary solution and stellar parameters of non-planet hosting stars in a planetary system. |
Dataset | 10.26133/NEA40 |
| K2 Planets and Candidates Table | This table replaced the K2 Candidates Table in November 2021. It contains all information in the archive on K2 planetary objects, both confirmed planets and candidates. | Dataset | 10.26133/NEA19 |
| Atmospheric Spectroscopy Table | This service replaced the Transmission and Emission Spectroscopy Tables in July 2023. All of the data in the retired tables were transferred to this table, and all newly ingested spectra are served from this table. | Service | 10.26133/NEA36 |
| Exoplanet Follow-up Observing Program (Unified Interface) |
The Exoplanet Follow-up Observing Program (ExoFOP) website is designed to optimize resources and facilitate collaboration in follow-up studies of exoplanet candidates. The separate ExoFOP portals for Kepler, K2, and TESS data were re-launched with a unified interface in April 2022. |
Service | 10.26134/ExoFOP5 |
| Transiting Planets Table | This table provides a simpler interface for accessing all of the transit-specific observables currently in the Exoplanet Archive. These data are a subset of what is available in the Planetary Systems and Planetary Systems Composite Data tables. | Dataset | 10.26133/NEA37 |
| Microlensing Planets Table | This table contains all microlensing-specific observational and model parameters for confirmed planets that were discovered with the microlensing technique. | Dataset | 10.26133/NEA38 |
| Kepler Objects of Interest (KOI) Cumulative Table | The Kepler Objects of Interest (KOI) Cumulative table gathers information from the individual KOI activity tables that describe the current results of different searches of the Kepler light curves. The intent of the cumulative table is to provide the most accurate dispositions and stellar and planetary information for all KOIs in one place. All the information in this table has provenance in other KOI activity tables. | Dataset | 10.26133/NEA4 |
| Kepler Objects of Interest DR25 Table | The Q1–Q17 Data Release 25 (DR25) Supplemental Kepler Objects-of-Interest (KOI) activity table reports dispositions based on the final processing (DR25) of the Kepler data and a combination of automated and human-based vetting to produce a "best-knowledge" catalog of planetary CANDIDATEs and FALSE POSITIVEs for use by the Astronomical community in selecting KOIs for follow-up observations and further study. | Dataset | 10.26133/NEA5 |
| Kepler Stellar Properties Table | The Kepler Stellar interactive table contains parameters for all targets observed by Kepler for the purpose of finding transiting planets. Individual tables include the values used for that specific processing, including the Q1–12, Q1–16, Q1–17 DR24, and Q1–17 DR25 pipeline runs. One additional table, the Q1–17 DR25 Supplemental Stellar, includes values provided by the Kepler Stellar Properties Working Group (SPWG) independent of any pipeline processing in order to report their most current stellar values. | Dataset | 10.26133/NEA6 |
| UKIRT Microlensing Survey | Light curves from the ongoing UKIRT microlensing survey made available with help from the UKIRT Microlensing Team. The Wide Field Camera (WFCAM) on the United Kingdom Infrared Telescope (UKIRT), located at Mauna Kea Observatory, has been used to conduct microlensing surveys with a variety of science goals. | Dataset | 10.26133/NEA7 |
| KELT Survey Light Curves | The Kilodegree Extremely Little Telescope (KELT) survey consists of two robotic telescopes that are conducting a survey for transiting exoplanets around bright stars. The NASA Exoplanet Archive currently contains about 1.1 million light curves in selected Northern fields. | Dataset | 10.26133/NEA8 |
| SuperWASP Survey Light Curves | SuperWASP consists of two robotic observatories that operate continuously throughout the year, allowing coverage of both hemispheres of the sky. The first, SuperWASP-North, is located on the island of La Palma among the Isaac Newton Group (ING) of telescopes. The second, SuperWASP-South, is located at the site of the South African Astronomical Observatory (SAAO), just outside Sutherland, South Africa. The NASA Exoplanet Archive hosts over 18 million light curves collected between 2004 and 2008. | Dataset | 10.26133/NEA9 |
| FDL INARA | This contributed data set contains 3,112,820 synthetic rocky exoplanetary spectra generated using the NASA Planetary Spectrum Generator (PSG), provided by team members from the 2018 NASA Frontier Development Lab astrobiology challenge #2. | Dataset | 10.26133/NEA41 |
| FDL pyATMOS | This contributed data set contains 124,314 model atmospheres for Earth-like planets, provided by team members from the 2018 NASA Frontier Development Lab astrobiology challenge #1. |
